Correctly aggregate together errors from nested config files (with
source-file). Fix by Thomas Adam, reported by Sam Livingstone-Gray

Call realpath earlier on the socket directory path rather than on the
socket file path because the latter may not exist yet and in that case
realpath is allowed to fail. From Romain Francoise.

xfree is not particularly helpful, remove it. From Thomas Adam.

Add a skeleton mode to tmux (called "control mode") that let's tmux
commands be sent and output received on stdout. This can be used to

Add a skeleton mode to tmux (called "control mode") that let's tmux
commands be sent and output received on stdout. This can be used to
integrate with other terminal emulators and should allow some other
things to be made simpler later. More to come so doesn't do much yet and
deliberately not documented.

Do not use stderr for log file and don't call log_close when not needed.

Simplify logging and just fprintf(stderr, ...) for early errors.

separate options, prefix and prefix2. This simplifies the code and gets

Drop the ability to have a list of keys in the prefix in favour of two
separate options, prefix and prefix2. This simplifies the code and gets
rid the data options type which was only used for this one option.

Also add a -2 flag to send-prefix to send the secondary prefix key,
fixing a cause of minor irritation.

People who want three prefix keys are out of luck :-).

Try to resolve relative paths for loadb and saveb (first using client
working directory if any then default-path or session wd).

Ignore LC_ALL and LC_CTYPE if they are empty as well as unset.

Reject $SHELL if it is not a full path.

Two fixes by Micah Cowan: make mouse work properly beyond >127 on signed
char architectures and properly parse $TMUX by stopping the socket path
at the first comma.

Set $TMUX without the session when background jobs are run.

Use TMPDIR if set, from Han Boetes.

Move all calls to fcntl(...O_NONBLOCK) into a function and clear the
flag on the stdio file descriptors before closing them (fixes things
like "tmux ls && cat").

Support for UTF-8 mouse input (\033[1005h). This was added in xterm 262
and supports larger terminals than the older way.

If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all
UTF-8 terminals. The option defaults to on if LANG etc are set in the
same manner as the utf8 option.

With help and based on code from hsim at gmx.li.

Change from a per-session stack of buffers to one global stack which is
much more convenient and also simplifies lot of code. This renders
copy-buffer useless and makes buffer-limit now a server option.

Add other-pane-height and other-pane-width options, allowing the width
or height of the smaller panes in the main-horizontal and main-vertical
layouts to be set. Mostly from David Goodlad.

In the built-in layouts, distribute the panes more evenly. Set the
default value of main-pane-width to 80, rather than 81. By Micah Cowan.

Add an option to alert (monitor) for silence (lack of activity) in a
window. From Thomas Adam.

If VISUAL or EDITOR contains "vi", configure mode-keys and status-keys
to vi.

Based on a diff from martynas@, previously requested by a couple of
other people.

Add XAUTHORITY to update-environment, requested by Andreas Kloeckner.

Merge the before and after attach client code into one in client.c
(instead of two in tmux.c and client.c).

Make stdio blocking again before calling shell command with -c.

Trying to set FD_CLOEXEC on every fd is a lost cause, just use
closefrom() before exec.
